The text and chapter headings include Original Edition page numbers and chapter numbers in [ ]; for example [ [212] Chapter I [VIII]. The page numbers of this edition, when present, are in the right margin.
Obvious typographical and punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources.
Inconsistent spelling of a word or word-pair within the text has been retained. For example, southeast south-east; gray grey; prairie dog prairie-dog.
Spelling has been left as found in the original text; variations in spelling and hyphenation have been left as well, except for those changes detailed below.
